Identifying the rose varieties and natural forms using ISSR-markers

Abstract

Identifying among varieties and natural forms of roses were carried out using ISSR thechnics to determine kinship. It was studied 6 foreign varieties, 16 varieties bred in Nikitsky Botanical Garden, as well as 2 natural forms (Rosa canina and Rosa chinensis). Despite some samples breaking into three clades, many of them don’t belong to any of these groups due to the lack of relative ties, that confirms the high genetic diversity in the studied material. The revealed molecular genetic differences in rose forms and varieties can be used to identify and certify cultivars promising for their complex resistance to the continental climate conditions.
